Locks – A Quick Homeowner’s Guide
Locks, like many other items in our homes, are objects we often take for granted until something goes wrong. Issues such as being locked out or experiencing lock failure (e.g. broken keys or mechanism faults) tend to arise when we’re least prepared.
This brief guide covers five essential points that are common to most households and may prove helpful when dealing with a locksmith.
What is BS 3621?
BS 3621 is a lock standard defined by the British Standards Institution (BSI). A BS3621-certified lock is classified as thief-resistant and is typically installed on external doors. For this reason, many insurance providers require homeowners to have these locks fitted to meet policy requirements.
What is a mortice deadlock?
A mortice deadlock is installed into a cut-out (or “pocket”) within the body of the door, aligning precisely with the door frame. Once fitted, it offers a neat, professional finish that protects the lock mechanism from tampering and exposure to the elements.
Operated by a key, this type of lock secures the property and can only be opened manually using the correct key.
Is a sashlock a type of mortice lock?
Yes. A sashlock, or mortice sash lock, provides the same security as a standard mortice deadlock but combines a latch, deadbolt, and handle mechanism in one unit.
Sashlocks are commonly used on both internal and external doors and are also fitted into the door body. They are a popular choice for homes requiring lever locks.
What is a night latch lock?
A night latch is a type of lock mounted on the surface of a door, typically on the interior side, rather than being recessed into the door. It can be deadlocked from the inside, which prevents the key from operating the lock externally.
Most night latches automatically lock the door when it is pushed or slammed shut, one of the most common reasons for accidental lockouts.
What is a hinge bolt?
Hinge bolts are security components designed to stop doors from being lifted off their hinges. Made from hardened steel, they resist sawing and forced removal.
They are especially important for outward-opening external timber doors and provide an added layer of protection against forced entry attempts.
